“Sistema per la regolazione di due alberi di trasmissione connessi mediante un albero cardanico” "System for adjusting two transmission shafts connected by means of a cardan shaft"
La presente invenzione si riferisce ad un sistema per la regolazione di due alberi di trasmissione connessi mediante un albero cardanico. The present invention refers to a system for adjusting two transmission shafts connected by means of a cardan shaft.
Dallo stato della tecnica è noto che per un'uniforme trasmissione del moto tramite un albero cardanico è necessario mantenere sempre il più possibile identici gli angoli d'entrata e d'uscita del moto. Le irregolarità prodotte da un giunto cardanico in questo modo si annullano a vicenda. Esistono, allo stato attuale della tecnica, meccanismi atti a mantenere albero motore e albero condotto in una configurazione tale per cui gli angoli di entrata e di uscita rimangono uguali durante l'impiego di tali macchine, ma tali meccanismi sono complicati. It is known from the state of the art that for uniform transmission of motion by means of a cardan shaft it is necessary to always keep the angles of motion entry and exit as identical as possible. The irregularities produced by a gimbal in this way cancel each other out. At the present state of the art, there are mechanisms suitable for maintaining the driving shaft and the driven shaft in such a configuration that the entry and exit angles remain the same during the use of such machines, but such mechanisms are complicated.
Dalla IT 1 379 11 1 è noto un sistema di compensazione da impiegarsi nella trasmissione di potenza tra un trattore comprendente un primo asse detto "albero motore" ed una trattrice comprendente un secondo asse detto "albero condotto", collegato ad una scatola d'ingranaggi fissata a detta trattrice in maniera girevole rispetto ad un asse sostanzialmente orizzontale ed ortogonale a detto albero condotto, detti primo e secondo asse essendo concorrenti e collegati da un albero cardanico, e formanti con esso rispettivamente un angolo alpha ed un angolo beta su di un primo piano sostanzialmente verticale, detto sistema comprendendo: - una prima coppia di supporti disposti in un secondo piano sostanzialmente verticale, di cui un primo supporto è solidale al trattore e presenta un punto di incernieramento, un secondo supporto è solidale alla scatola d'ingranaggi e presenta un punto di incernieramento, detti primo e secondo supporto essendo rispettivamente in posizione sfalzata rispetto all'albero cardanico; una seconda coppia di supporti disposti in un terzo piano sostanzialmente verticale ed opposto a detto secondo piano verticale rispetto all'albero cardanico, di cui un terzo supporto è solidale al trattore e presenta un punto di incernieramento, un quarto supporto è solidale alla scatola d'ingranaggi e presenta un punto di incernieramento, detti terzo e quarto supporto essendo rispettivamente in posizione sfalsata rispetto all'albero cardanico ed opposta rispetto a detti primo e secondo supporto potendo variare la propria lunghezza ed essendo tra loro vincolati a mantenere sostanzialmente uguali le rispettive lunghezze, la disposizione essendo tale che detti angoli alpha e beta risultino uguali in ogni condizione operativa. From IT 1 379 11 1 a compensation system is known to be used in the transmission of power between a tractor comprising a first axis called "driving shaft" and a tractor comprising a second axis called "driven shaft", connected to a gear box fixed to said tractor in a rotatable manner with respect to a substantially horizontal axis and orthogonal to said driven shaft, said first and second axes being concurrent with and connected by a cardan shaft, and forming with it respectively an angle alpha and an angle beta on a first substantially vertical plane, said system comprising: - a first pair of supports arranged in a second substantially vertical plane, of which a first support is integral with the tractor and has a hinging point, a second support is integral with the gearbox and has a hinging point, said first and second supports being respectively in offset position with respect to ab I was gimbal; a second pair of supports arranged in a third substantially vertical plane and opposite to said second vertical plane with respect to the cardan shaft, of which a third support is integral with the tractor and has a hinging point, a fourth support is integral with the housing gears and has a hinging point, said third and fourth supports being respectively in offset positions with respect to the cardan shaft and opposite to said first and second supports, being able to vary their length and being constrained to each other to keep the respective lengths substantially the same, the arrangement being such that said angles alpha and beta are the same in every operating condition.
Questo sistema pur presentando notevoli vantaggi è ancora troppo complesso nella realizzazione e regolazione. Although this system has considerable advantages, it is still too complex in its construction and regulation.
Lo scopo della presente invenzione è di migliorare il sistema di regolazione dell'angolo di entrata del moto condotto con flessibilità massima nella trasmissione. The object of the present invention is to improve the system for adjusting the entry angle of the driven motion with maximum flexibility in the transmission.
Questo scopo viene raggiunto da un sistema per la regolazione reciproca di due alberi di trasmissione connessi mediante un albero cardanico, il primo albero essendo azionato da una macchina la cui uscita di forza di è collegata ad un albero cardanico mediante un giunto cardanico, detto albero cardanico essendo collegato a un secondo albero, rappresentato da una presa di forza di una scatola a ingranaggi a rinvio angolare di una trinciatrice/fresatrice, la scatola a ingranaggi a rinvio angolare azionando almeno un utensile di lavorazione, e che la scatola a ingranaggi a rinvio angolare e collegata al telaio della trinciatrice/fresatrice mediante almeno due braccetti per permettere sia una rotazione attorno ad un asse sia uno spostamento trasversale in modo che il secondo albero sia sempre disposto in modo che gli assi “ideali” di entrambi formino un triangolo isocele. This purpose is achieved by a system for the mutual adjustment of two transmission shafts connected by means of a cardan shaft, the first shaft being driven by a machine whose force output is connected to a cardan shaft by means of a cardan joint, called cardan shaft. being connected to a second shaft, represented by a power take-off of an angular drive gearbox of a shredder / milling machine, the angular drive gearbox driving at least one machining tool, and that the angular drive gearbox and connected to the frame of the shredder / milling machine by means of at least two arms to allow both a rotation around an axis and a transverse movement so that the second shaft is always arranged so that the “ideal” axes of both form an isoceles triangle.
In una forma di realizzazione preferita i braccetti sono disposti a 10°-170° fra l'uno e l'altro. In questo modo l'asse del secondo albero nella posizione iniziale e sostanzialmente parallelo colinare del primo albero. In a preferred embodiment, the arms are arranged at 10 ° -170 ° between one and the other. In this way the axis of the second shaft in the initial position is substantially parallel to the line of the first shaft.
Inoltre questo sistema è particolarmente vantaggioso per macchine che svolgono sia il compito di trinciare che fresare, poiché gli angoli per effettuare la lavorazione sono differenti. Con il sistema secondo l'invenzione è possibile regolare più facilmente l'angolo dei utensili mediante la scatolo di ingranaggio angolare che può essere sia ruotata che spostata. Per regolare la posizione può essere previsto un timone a lunghezza variabile. Furthermore, this system is particularly advantageous for machines that perform both the task of shredding and milling, since the angles for carrying out the processing are different. With the system according to the invention it is possible to more easily adjust the angle of the tools by means of the angular gearbox which can be both rotated and moved. A variable length drawbar can be provided to adjust the position.
All'ingranaggio angolare possono essere collegati anche più rotori in serie portanti attrezzi. Several rotors carrying tools can also be connected to the angular gear.
Ulteriori caratteristiche risultano in modo non limitativo dal disegno e dal descritto preferito esempio di realizzazione in cui mostrano: Further characteristics result in a non-limiting way from the drawing and from the described preferred embodiment example in which they show:

la Figura 4 una trasmissione angolare, Figure 4 an angular transmission,
la Figura 5 una vista dall'alto del collegamento fra macchina trainante e fresatrice/trinciatrice Figure 5 is a top view of the connection between the driving machine and the milling / shredding machine
la Figura 6 una sezione della Figura 5, Figure 6 is a section of Figure 5,
la Figura 7 una sezione del collegamento macchina e trinciatrice/fresatrice, e Figure 7 a section of the machine and shredder / milling machine connection, e
la Figura 8 una trasmissione angolare fissata secondo l'invenzione in una fresatrice/ trinciatrice. Figure 8 an angular transmission fixed according to the invention in a milling machine / shredder.
Nella Figura 1 è indicato con il numero di riferimento 100 una macchina, in modo preferito un trattore. A questo trattore 100 e collegato una fresatrice/trinciatrice 1. Questo collegamento per mezzo di barre 4 serve a trainare la trinciatrice/fresatrice. Inoltre la macchina 100 trasmette una coppia motore attraverso un albero 5. Questo albero 5 è collegato mediante un albero cardanico 8 a un albero di trasmissione 7 che alimenta una scatola ad ingranaggi angolare 9 che è atta ad essere collegata in uscita almeno ad un porta-utensile, che porta per esempio utensili per trinciatura o fresatura. In Figure 1, the reference number 100 indicates a machine, preferably a tractor. A milling machine / shredder 1 is connected to this tractor 100. This connection by means of bars 4 is used to tow the shredder / milling machine. Furthermore, the machine 100 transmits a motor torque through a shaft 5. This shaft 5 is connected by means of a cardan shaft 8 to a transmission shaft 7 which feeds an angular gear box 9 which is adapted to be connected at the output to at least one carrier. tool, which carries for example tools for cutting or milling.
L'albero 5 e l'albero 7 devono essere disposti in un triangolo isoscele per garantire un funzionamento ottimale. Shaft 5 and shaft 7 must be arranged in an isosceles triangle to ensure optimal operation.
Questa scatola ad ingranaggi 9 è collegata con il telaio della fresatrice 1 secondo l'invenzione mediante almeno due braccetti 41,42. Questi due braccetti 41,42 permettono sia che la trasmissione angolare possa essere ruotata attorno a un'asse This gear box 9 is connected to the frame of the milling machine 1 according to the invention by at least two arms 41,42. These two arms 41,42 allow both that the angular transmission can be rotated around an axis
In questo modo si può mantenere l'albero 5 e l'albero 8 sostanzialmente formano un triangolo isoscele. In this way, shaft 5 and shaft 8 can be kept substantially forming an isosceles triangle.
Inoltre questa regolazione è particolarmente vantaggiosa per macchine combinate trinciatrice/fresatrice, poiché l'angolo degli utensili deve essere cambiato fra il procedimento di trinciatura e fresatura. Furthermore, this setting is particularly advantageous for combined shredder / milling machines, since the angle of the tools must be changed between the shredding and milling process.
La regolazione della scatola ad ingranaggio angolare può avvenire in modo preferito per mezzo di un timone 10. In Questo modo può essere regolato sia la distanza dal telaio della trinciatrice/fresatrice che l'orientamento. The adjustment of the angular gearbox can preferably be carried out by means of a drawbar 10. In this way, both the distance to the frame of the shredder / milling machine and the orientation can be adjusted.
Questo timone 10 può essere telescopico per permettere una sua regolazione più facile. This rudder 10 can be telescopic to allow for easier adjustment.
Il sistema secondo secondo l'invenzione in una form di realizzazione definisce che il rapporto fra la lunghezza dalla uscita di forza 3 e il centro di rotazione 15 fra l'uscita di forza 3 e la presa di forza 13 e la lunghezza dal centro di rotazione 15 fra l'uscita di forza 3 e la presa di forza 13 e la presa di forza 13 rimane costante. The system according to the invention in one embodiment defines that the ratio between the length from the power output 3 and the center of rotation 15 between the power output 3 and the power take-off 13 and the length from the center of rotation 15 between the power take-off 3 and the power take-off 13 and the power take-off 13 remains constant.
